    Yes, it barfed. I can tell you from experience that that year had a problem with needles getting out of the wrist pin bearings and jamming between the piston and cylinder wall, causing severe damage. But that does not mean for certain that is what happened in this case. It has to come apart to evaluate the damage. Sorry ’bout that.

    EDIT: Some of the first steps in a complete powerhead disassembly are removal of flywheel and cylinder head. By the time you get that far, you will have a pretty good idea of what happened.
